Conventional cotton breeding involves hybridization and selection following a pedigree record performance of the progenies. The process is cumbersome and time-consuming as one variety takes at least 10 years to reach the stage of final release to the farmers for commercial cultivation. Sophistication in breeding methods has led to the introduction of genetic and cytoplasmic male sterility in cotton. With the advent of the male sterility system, the evolution of F hybrid cotton has become possible, reducing this time-consuming task to two or three years.
